I COMBINED CII-TURN A-NDBUTTER-WORKER.

T all whom t may concern.' Y

Beit known that I, REUBEN 2B. Drsnow, a citizen of the United States, residing at StLv Paul, in the county lof Ramsey andv State of Minnesota, have invented certain new and useful Improvements in Combined Ghurn and VButter-lorkers; and I dov hereby declare the following to be a full, clear,`and exact description of the invention, suchas will enable others skilled in the art to which it Yappertains to Vmake and use the same. A

My invention has for itsobject to provide an improved combined churn and A butter worker; and to such ends, generally stated, the invention consists of the novel devices and Y combinations of devices hereinafter Vdescribed and defined in the claims.

The invention consists of a novel relative Varrangement of drum, working rollers, lifting flights and'driving connections wherebythe butter will be Worked four times in each rotation of the drum. This result is obtained by the use of two lifting flights and four working rollers grouped. around the axis of the drumA and driven so as to cause the butter to be worked twice between rollers, under the upwardl movement of each iight or'four times for eachrcomplete lrotation of the drum.

A commercial form of thisv combined.

churn and butter worker is'illustrated in the accompanying drawings wherein like characters indicate like parts Athroughout the several views.

' Referring to the drawings Figure 1 is an end elevation of the ma-l chine 'showing particularly the driving con-' nection for the drum and" rollers; and v F ig; 2 isa transverse vertical section taken through the intermediate frportion of the dru'm.v i n The drum 3, which'is ofthe usual conl struction provided with an ordinary door 4,

Y is mounted to rotate on the horizontal. aXis in a well known manner on ksuitable end pedestals 5 and 6 connected by tie bars 7. On one head, the Vdrum 3 is provided with a if large annular sprocket v8. A, sprocket chain Specification of Letters Patent.

ally spaced on' 17ibut i' as the two .y chains 111 and 15 and the cooperating sprockets are for the relative low andhigh speeds of they drum, resp`e`ctiv ly,ffor butter ,working, and` churning actions, and are of the well known arrangement, itis' suicient "for the purposes of this case' to state that theyare 'y intended torotate the drum in the direction of the arrows'marked thereon Vin F ig. v1,

when the shaft 17 is driven in the same di-y Located within the drum in diainetrically opposite arrangement, are two butter lifting nights or shelves'19 that deliverl the butter on the rising side of the drum to a group of four deeply corrugated paddle-like working rollers 20. y,These rollers 20 are spaced equidistant fromV the axis of the drum nd are grouped around thedruni in rectangular arrangement, 'and their shafts 21are provided outside `of "the drum head with sprocket wheels 22.v VAll of thesel sprockets 22 are inside of the Varms of thespider-like bracket 23 Ashown as secured to the annular sprocket S. Journaled in the bracket 23 at the axis of the drum, is a short countershaft 24 which,

provided with al sprocket '26. A sprocket' Chain 27 runs over the outside sprocket'25 -o'utsideuof thelo'racket, is provided witha n sprocket 25v and inside of said bracketlis and over one of the three elements 16 on theV l driving shaft 17. A short sprocket chain 28 runs over theinside sprocket 26 and over a sprocket 29 that is secured to one ofthe rollershafts 21v outward of its sprocket' 22 but inside'of 'the"bracket`23.` Ai `sprocket chain()VV runs over the sprocket 22 of the roller shaft 21 that is equipped with a sprocket 29, and also over the sprocket 22 ofV the diametrically opposite roller shaft 21.

This chainBO runs against the inner sides of the other twoV sprockets 22 s'othat the four rollers 20 will be driven in the direction of the arrows marked adjacent thereto on Fig. 2. reference to Fig. 2, it will be noted that' the two vertically spaced rollers n to the particular position of the rollers'y shown in Fig. 2. The vimportance of the Y i Vzo grouping of the rollers and of the driving'of- "the same, as 'described-will appearl in the description ofthe operation.

IClutches,andthe like, for 'throwing the rollers into'and out'of action, arrangedsub- -each rotation of the dru 2. The combinationwith a druinY arrangedVY stantiallyas usedin anyL of; the well known driving connectlons in combined churns and butterv workers, may bev employed and'it will,I

of course, be understood that, in the churn-1 ing action, it is not necessary to drive the A rollers, but that they must be driven 1n the' .l vbutter'working action; The-chainaction is goltwious,v but the butter worklng action,

' whichinvolves new operation and a highly improved result(V is asv follows' Y Onthe rising side of the drum, the butter will be llifted by the upwardly moving flight i or. shelf l19 a1'id` will be delivered between i so' tion'of the two oppositelyfrmoving rollers, first as indi- "cated by the arrows marked a on Fig. 2,' and second, between oppositely rotating rollers, as indicated by the arrows marked b on Fig. 2. Thus'it will be seen thatthe butter, Vin

the upward movement fof' the first noted'- flightand under the first-half rotation of thedrunnwill twicebe' worked betweenico'- operatingV reversely rotating working rollers.

On the second half rotation of thedrum, the same action takes place between the other two rollers, so that'under ya' Vcomplete rota-k crum, the butter -will be worked fourK4 times etween "cooperating reversely rotating rollers. This gives a much better butter lWorking action than hithertoV accom'- plished with 'the butter workers known to me;v Moreover, the result is VAaccomplished vbyV an extremely ysimple, construction and by veryfdesir'able equi-distant grouping of the Y f6.6 the centrifugal action vtending rollers around the axis of the drum whereby an' approxi matelyY constant continuous and e Y v 'i to'A rotate lonf'an approximately horizontal axis, of diametrically opposite lifting flights even butter working-faction is produced.

VIn the drawings I have, in a general way, illustrated means forhigh and low speeds of thedrum, respectively, for the churn and butter .worker actions, but inrpractice, I do not believe lthatthis'two-speed is required,

because'the plurality of rollers, co-'acting' with the liftingflights,which act as dashf` ers-in the churning action produce such` great-agitation of the milk that I believe' that churning atmaximum speed and maxi-` i'numeftlciency as to separation of the butter .i f fat, may be accomplished by running the drumatV the lower speed with the rollers in action ,to produce the churning. action. In fact, toovhighv speed of the drum in the churning action has a tendency to defeat the object, towit, rapid churningfbecauseof to cause the milkto. cling to the drum.
